--- Comment #20 from Vitaly Magerya <vmagerya@gmail.com> ---
Evdev devices should already have an IOCTL that exposes that
information; see 'libevdev_has_event_type' and 'libevdev_set_fd'
over at [1].

For example, if 'libevdev_has_event_type(device, EV_ABS)' is
true, then it's a touchpad. (Maybe an additional test for
'libevdev_has_event_code(evdev, EV_KEY, BTN_TOUCH)' being true
is also needed, I'm not sure).

I think this can be corrected later -- if this patch will be
accepted at all, improving it will be easy enough from there.
